Wet system features: ① simple structure, reliable ② system construction is simple, flexible and convenient ③ fire speed, high efficiency ④ fire control system investment, more economical ⑤ wide range of applications and open closed nozzle jets.... The main difference is: closed nozzle with a release mechanism, and open sprinklers not release mechanism. Glass bulb sprinklers. Glass bulb sprinklers by a water spout, glass balls, frame, deflector, gaskets and other components. Glass balls are heat-sensitive element a certain amount of built-in color expansion of the fluid, also called nozzle release mechanism, FM spray product, inside the ball a little bubble, under normal conditions, the glass ball against the nozzle gasket, when a In case of fire, the liquid inside the heat expansion of ball pressure increases, when the pressure reaches a predetermined value, Shandong FM spray products, glass ball burst, gaskets loss of support, pressure water spray fire. FM spray products, a Anyuan Industrial (online consultation), Shandong, Hubei FM spray products from creating Anyuan Electrical Equipment Co., Ltd. to provide.
